Re: libdvdread has trouble with some DVD images

Continuing my investigation, I commented out the offending assert and 
got to another one:

tccat: ifo_read.c:831: ifoRead_TT_SRPT: Assertion 
`(int)tt_srpt->nr_of_srpts * sizeof(title_info_t) <= info_length' failed.

After adding some fprintf's I found that:
    tt_srpt->nr_of_srpts = 3
    sizeof(title_info_t) = 12
    info_length = 24

If I comment out that assert I get a segfault.  I tried the following 
modification but it still segfaults:

  if ((int)tt_srpt->nr_of_srpts * sizeof(title_info_t) > info_length)
      tt_srpt->nr_of_srpts = info_length / sizeof(title_info_t);
